Sub wiring

I just purchased 1 12" Ma Audio(MA12XE) sub in which I am making the enclosure for. On the sub there are two sets of wiring terminals(2 neg, 2 pos)located on each side of the sub. How would I go about wiring this up? Am I to use both terminals or only 1? Thanks all...

That means it's a DVC (dual voice coil sub). One set is a positve and negative and the set on the other side is also a positive and negative. Guessing the subs are dual 4 ohms (most DVC are), then you can wire your sub to either 8-ohms or 2-ohms. You have to use both or the sub won't work. If you wire from positive to positve and then to the positive on the amp, and negative to negative and then to the negative on the amp, you're running the sub down to 2-ohms. If you wire positive to negative and then to the negative on the amp, and negative to positive and then to the positive on the amp, you're wiring the sub to 8-ohms. If you want more bass and your subs can handle the power, then wire them to 2-ohms apeice and bridge them to the amp at 1-ohm, but only if the sub can handle the power, and the amp is capable of taking a 1-ohm load.

Thanks allot. Very informative.

No prob, any more questions just ask.

You can run dvc subs w/ one coil.

edit: <---- I'm w/ stupid.

true, but its not recommended. if you run the same amount of power through one coil, you run the risk of putting too much current through the wire and burning it out. you would also be wasting half of the subs potential.

Goddamn it DO NOT RUN DVC w/ only one coil...
It worked for me for a bit .. then one of them dies. Gunna cost over $100 to fix it the guy who sold it to me says. The reason being the wires in side are inter twinded around the electromagnet when only a bit of power is run through one of them that one expandds pushing out the other one on to the outtter case shorting it out....
